This page is obsolete and kept only for historical interest. It may document features that are obsolete, superseded, or irrelevant. Do not rely on the information here being up-to-date.

VLS (aka VideoLAN Server) is an outdated streaming solution. More information is available on http://www.videolan.org/vlc/streaming.html.

Unless you really know what you are doing, we advise that you use VLC instead as it is far more powerful than VLS.

Known problems

VLS isn't compatible with GCC 4. You will thus need to use GCC 2.9, 3.3 or 3.4 to compile, or submit a patch to fix compilation problems on GCC 4.

Solutions

Mandrake Patch

Mandrake Linux supplies a patch for vls 0.5.6 that fixes compilation on gcc 3.4. The patch also works for gcc 4+ (Tested with 4.0.2 & 4.1.2). The patch file (vls-0.5.6-gcc34.patch from vls-0.5.6-5mdk.src.rpm):

libdvbpsi

Use libdvbpsi3-0.1.4. Later versions have incompatible API changes.

Dependency Errors

This error indicates that Makefile.dep and Makefile.module.dep need to have some spare newlines removed. See this forum thread for details.
